Creating an email account in cpanel is rather easy. After you have logged into cpanel click on the mail icon

Now it should have a list of options (webmail, email domain forwarding, etc) well click where it says"Manage/Add/Remove Accounts"
On the way bottom it should say:[ Add Account ] | [ Go Back ]
This is when you click Add Account

Now just fill in 'Email' and create a 'Password" then click CREATE.However if you are hosting more then one domain/subdomain you will have an option to change the domain.

Then to read you're mail just go into you're cpanel --> manage mail --> read mail. Or just go to http://yourdomain.com/webmail and type the username and password!
